Our Technical Services
Toxicology Services
General toxicology
Our regulatory toxicology experts assess the potential for substances and products to cause adverse effects on human health. We provide expert interpretation of toxicological data, identify hazards and support the preparation of robust regulatory submissions in line with global regulatory requirements.
Specialist toxicology
RSA’s toxicology specialists provide specialist toxicology expertise for complex regulatory challenges including carcinogenicity, developmental and reproductive toxicity (DART), genotoxicity, mechanistic toxicology and other endpoints requiring detailed scientific evaluation. Our team supports study design and interpretation, weight-of-evidence assessments and regulatory strategy to help clients address specific toxicological concerns.
Pathology
Our pathology specialists provide expert evaluation and interpretation of histopathology findings from toxicology studies. By identifying treatment-related effects and distinguishing them from incidental findings, we help ensure accurate study interpretation and support sound regulatory decision-making. RSA also has experience in assembling Pathology Working Groups for a detailed independent peer-review of specific pathological findings.
Endocrine Disruption
We offer comprehensive support for the assessment of endocrine-disrupting (ED) properties in accordance with current EU regulatory requirements, including CLP classification. From study design and data interpretation to regulatory submissions and expert scientific advice, we help clients navigate this complex and evolving area of toxicology.
Dermal Absorption
Understanding how substances are absorbed through the skin is essential for realistic human health risk assessment. Our dermal absorption specialists provide expert advice on design, data evaluation and regulatory interpretation to support exposure assessments across a range of product sectors.
Metabolism and Kinetics
Our metabolism and toxicokinetics specialists assess how substances are absorbed, distributed, metabolised and excreted from the body. These evaluations provide critical insight into a substance’s behaviour and support hazard identification, dose selection and regulatory risk assessment.
QSAR Evaluation
We conduct expert QSAR (Quantitative Structure–Activity Relationship) evaluations to predict the toxicological properties of substances where experimental data may be limited. Using scientifically validated models and weight-of-evidence approaches, we support regulatory submissions while helping to minimise animal testing.
Hazard Classification
RSA toxicologists have expertise in hazard classification under CLP for substances and products. Our experts have represented clients at ECHA (RAC) and have successfully defended substance classification proposals.
Other Services
Non-Dietary Exposure
RSA specialists have specific expertise in the assessment of non-dietary exposure for pesticide and biocide products, using the latest guidance, models and refinement options.
Consumer exposure & Residues
RSA works with trusted partners to deliver services in the area of consumer exposure to pesticide residues. RSA also has experience in developing residue definition proposals for pesticides and works with trusted partners in other areas of residue assessment.
Ecotoxicology
RSA specialists can support your projects in the area of ecotoxicology, and have specific expertise in the area of bee, soil invertebrate and non-target arthropod testing and assessment.
Environmental fate
RSA consultants have experience in the assessment of environmental fate and behaviour of molecules, and can help clients in the pharmaceutical, chemical and agrochemical sectors.
Analytical methods
Appropriate analytical methodology is essential to successful regulatory studies. RSA specialists can offer support in this area, building on expertise gained from industry.
